Method and system for detecting safety of lifting iron ladles and steel ladles by crown block

Abstract

The invention relates to a method and system for detecting safety of lifting iron ladles and steel ladles by a crown block. The detecting method comprises the steps of creating coordinates for the internal space of each bay where the crown block passes and recording coordinate data into a system database; then accurately positioning the crown block in the horizontal direction and vertical direction to obtain operation coordinate records of the crown block; and finally analyzing the operation coordinate records of the crown block and weighing value changing behavior during lifting-up and putting-down to complete tracking of the specific iron ladles and steel ladles. The detecting system comprises a real-time data acquisition module, a logical judgment module, an alarm execution module, a tracking display module, a terminal, and a data storage module. The detecting method and system can detect abnormal situations in the process of lifting the iron ladles and the steel ladles by the crownblock and give an alarm, thereby increasing the safety of lifting operation of the iron ladles and the steel ladles; and the detecting method and system have the characteristics of applicability, safety and high efficiency.

Description

technical field [0001] This patent application belongs to the technical field of crane logistics safety monitoring, in particular to a safety detection method and system for hoisting and transporting iron and steel ladles by crane. Background technique [0002] The iron (steel) ladle is the main container for the transportation, transfer and smelting of molten iron (steel) in the steelmaking area. The method of whether the iron ladle is safe is mainly to rely on manual visual inspection on both sides of the ladle. With the continuous acceleration of the pace of steelmaking production, the lifting operation is becoming more frequent, and manual visual inspection is sometimes affected by poor vision at night and poor mental state. Influenced by factors such as poor sense of responsibility and weak sense of responsibility, the crane bag is not firm, the hook and trunnion do not match, the bag is not aligned when putting the bag, or the small damage and deformation of the equipm...

[0002] The iron (steel) ladle is the main container for the transportation, transfer and smelting of molten iron (steel) in the steelmaking area. The method of whether the iron ladle is safe is mainly to rely on manual visual inspection on both sides of the ladle. With the continuous acceleration of the pace of steelmaking production, the lifting operation is becoming more frequent, and manual visual inspection is sometimes affected by poor vision at night and poor mental state. Influenced by factors such as poor sense of responsibility and weak sense of responsibility, the crane bag is not firm, the hook and trunnion do not match, the bag is not aligned when putting the bag, or the small damage and deformation of the equipment cannot be found, resulting in the tipping of the iron (steel) bag , and iron (steel) heavy bag overturning accidents will cause serious personal injury and equipment damage, which have happened many times in history
